This is my first AR that I picked up from my local gun shop, and I’m still trying to fully understand California compliance laws. I’m not very knowledgeable yet, so I want to make sure I’m not doing anything wrong.
From what I understand, it has a detachable magazine and what looks like a pistol grip, but I’m not completely sure. I’m confused about the whole “featureless vs fixed magazine” thing and what that means for my setup.
Can someone help me confirm whether this is California compliant? I just want to make sure everything is legal and I don’t get myself into trouble.
